Next add support in the config help file. Edit config/Configure.help and add the helloworld part as shown below. NOTE: there must be two spaces before text in the comments, which cannot be more than seventy characters long.

The application can now be found in top of the Miscellaneous Application menu
If the directory contains several binaries another line can be added, where the last "HELLOWORLD" is the name of the binary file to be included.
